Oracle price deviation >X% from secondary
Lido's assessment for RD-F-099 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Lido's AccountingOracle is a committee oracle, not Chainlink. The analogous deviation check is stETH/ETH exchange rate vs Curve pool spot price. Currently within ~0.2% of peg. Structural yellow: Curve stETH/ETH liquidity declined from ~$800M to ~$274M post-Shapella, raising peg sensitivity. May 2025 Chorus One oracle key compromise demonstrated oracle is a targeted attack surface (5-of-9 quorum held). Signal requires custom implementation for committee oracle vs Curve spot comparison.
